I really like the cowl vent grille but I'm taking out my OEM heater box and was faced with trying to figure out what to put in place of the vent grille. Welding in a new flat piece of metal was going to warp the heck out of the cowl and I really want to move forward from all this bodywork. The vent was really the cause of the floor rusting so bad because of the big drainage hose that went into the passenger side kick panel.

I decided to bend up a piece of sheet metal and make it into a drain to weld in place of the air box for any water that might go into the vent.
